“…Several studies conducted in contaminated aquatic systems have reported a correlation between the concentration of metals in sediment and in the resident fauna (Pourang, 1996;Solà et al, 2004;Murphy & Davy-Bouker, 2005;Solà & Pratt, 2006;Dural et al, 2006;Corbi et al, 2011) as a result of bioaccumulation and biomagnification processes (Corbi et al, 2010). Toxic effects of metals can occur at the individual level, for example, increasing mortality of sensitive species and also changing other vital processes such as growth and reproduction (Casper, 1994;Amisah & Cowx, 2000;Chanu, et al, 2017).…”

Aquatic insects as bioindicators of heavy metals in sediments in Cerrado streamsAquatic insects are the most widely used organisms in freshwater biomonitoring of human impacts and can provide reliable information on habitat and water quality. The Brazilian Cerrado has received strong anthropogenic impacts over the last decades, including the massive use of fertilizers in agriculture containing different concentrations of metals, with high potential of aquatic ecosystem contamination. In this context, this paper compared bioaccumulation of heavy metals among four trophic groups of aquatic insects from Cerrado streams. Sampling of sediments and aquatic insects for metal analysis (Cu, Mn, Cd and Zn) and for the bioaccumulation factor (BAF) calculation was performed from April to July, 2012. All metals were found in the stream sediments. Analysis of variance (ANOVA) showed no differences in metal concentrations among feeding guilds for Zn and Cu (F3,8 = 0.045; p > 0.005; H = 4.641; p > 0.005 respectively). With respect to manganese, the predators accumulated significantly lower concentrations than collector gatherers (F3,8 = 20.416; p < 0.05, Tukey < 0.05). Cadmium was not detected in the fauna. The results of the present study suggested that the use of aquatic insects as bioindicators might be an important strategy to detect metal pollution in aquatic environments.

“…Studies conducted in different metal-contaminated aquatic systems have reported the presence of the metals in sediment and negative effects in the benthic fauna (Murphy & Davy-Bowker, 2005, Dural et al, 2006, Solà & Pratt, 2006, Corbi et al, 2011, Zhang et al, 2016. Toxic effects of metals can occur at the individual level, for example, increasing mortality of sensitive species and changing other vital processes such as growth and reproduction (Casper, 1994, Amisah & Cowx, 2000, Chanu et al, 2017. Similarly, the exposure of insect larvae to the sediment of streams located in agricultural areas reduced the number of DNA bands, causing a loss of genetic diversity (Colombo-Corbi et al, 2017).…”

The relationship between sediment metal concentration and Odonata (Insecta) larvae assemblage structure in Cerrado streamsMetals can be incorporated into stream sediment affecting benthic invertebrate assemblages in different ways. Odonata larvae have variable tolerances to metals; sublethal levels accumulated in larval tissue can indirectly influence assemblage structure in environments with differences in types and concentrations of metals in the sediment. This research evaluated the relationship between Odonata larvae assemblages and sediment metal content in Cerrado streams. We evaluated genus composition, abundance, richness, Shannon-Wiener (H') diversity index and Pielou's evenness index (J') of the assemblages from 12 streams. Cluster analysis was used to identify groups of streams according to sediment concentrations of Cu (copper), Zn (zinc), Ni (nickel), Fe (iron) and Mn (manganese). Canonical Redundancy Analysis (RDA) and Canonical Correspondence Analysis (CCA) were performed to determine how metals influence Odonata assemblage metrics. Cluster analysis revealed three distinct groups of streams according to metal concentration in the sediment. RDA showed a negative relation between Pielou evenness (J') and the concentration of Ni, Cu, Zn and Mn, while abundance, genus richness and Shannon-Wiener diversity were positively related with Fe. CCA indicated that some taxa showed an opposite relation with metal concentration, but others were more abundant in streams subjected to high metal concentrations. Although the increase in iron concentration in streams can lead to an increase in the abundance of Odonata larvae, high concentrations of coper, zinc and manganese can lead to a reduction in taxon evenness.

As water pollution poses an increasing risk worldwide, it is timely to assess the achievements of the aquatic macroinvertebrate ecotoxicology to provide a sound basis for the discipline’s future and support the development of biomonitoring. Aquatic and semi-aquatic bugs (Hemiptera: Nepomorpha, Gerromorpha) are ubiquitous in almost all water types, sometimes in high densities, and play a significant role in organic material turnover and energy flow. Nevertheless, they are ignored in the water pollution biomonitoring schemes. Here, based on 300 papers, we review and evaluate the effects of chemical pesticides, microorganism-derived pesticides, insecticides of plant origin, heavy metals, eutrophication, salinisation and light pollution which are summarised for the first time. Our review encompasses the results of 100 laboratory and 39 semi-field/field experiments with 47 pesticides and 70 active ingredients. Pyrethroids were found to be more toxic than organochlorine, organophosphate and neonicotinoid insecticides to water bugs, like other macroinvertebrate groups. Additionally, in 10 out of 17 cases, the recommended field concentration of the pesticide was higher than the LC50 values, indicating potential hazards to water bugs. The recommended field concentrations of pesticides used in mosquito larvae control were found non-toxic to water bugs. As very few replicated studies are available, other findings on the effects of pesticides cannot be generalised. The microorganism-derived pesticide Bti appears to be safe when used at the recommended field concentration. Data indicates that plant-derived pesticides are safe with a high degree of certainty. We have identified three research areas where water bugs could be better involved in water biomonitoring. First, some Halobates spp. are excellent, and Gerris spp. are promising sentinels for Cd contamination. Second, Micronecta and, to a certain extent, Corixidae species composition is connected to and the indicator of eutrophication. Third, the species composition of the Corixidae is related to salinisation, and a preliminary method to quantify the relationship is already available. Our review highlights the potential of water bugs in water pollution monitoring.
